Definitions
- the present invention relates to a connection element for two components of a conveyor support or guide structure.
- connection elements In known connection elements the means for fixing the connection element to a tubular component of the conveyor structure are positioned externally in the lower part of the element, spaced from and perpendicular to the longitudinal axis of said tubular component.
- these fixing means can be operated only laterally, they considerably limit the application of the connection elements, which can be used only if they lie in a position in which there is sufficient space to tighten said fixing means.
- the fixing means comprise a nut and a bolt, which requires the use of two tools to fix the connection element to the tubular component and further complicates this operation.
- connection element for connecting a second component of the conveyor support structure other than the tubular component, generally allow only a limited scope for positioning said second component in different angular positions in the same plane.
- An object of the present invention is to provide a connection element which (a) simplifies and accelerates the operations involved in connecting such connection element to a tubular component of a conveyor, (b) enables this connection to be made even when used in narrow or laterally difficultly accessible spaces, and (c) enables the second connected component to be better and more easily positioned.
- connection element in accordance with the invention described below.
- FIG. 1 is a top perspective view of a connection element according to the invention
- FIG. 2 is a rear elevation view thereof
- FIG. 3 is a section therethrough taken on the line 3 / 3 of FIG. 2 .
- a connection element of the invention comprises a body, indicated overall by 1 , presenting a first part 2 comprising first means 3 for removeable attachment to a substantially flat portion 15 A of a first component 15 of a conveyor (not shown), and a second part 5 comprising second means 6 for removably fixing a tubular portion 7 A of a second component of the conveyor.
- the first part 2 of the body 1 presents a flat element 2 A of oval shape, integral with the second part 5 and connected to this latter part by two webs 2 B, and an intermediate part 2 C.
- the flat element 2 A presents two apertures 3 A concentric with each other and with a center C of the element 2 B, and extending through an equal portion of circumference T 1 .
- the two apertures are symmetrical about a horizontal axis 0 of the flat element 2 B.
- the two apertures 3 A enable the component 15 , fixed to the flat element 2 A by conventional nuts and bolts 7 A, B (FIG. 3) passing through said apertures, to be rotated about the center C of the flat element.
- slots 3 A In addition to the two concentric slots 3 A, further slots could also be provided (shown dashed in FIG. 2) having the same center C but of different radius (FIG. 3 ), or disposed vertically ( 3 C), or horizontally ( 3 D).
- the second part 5 of the body 1 presents a substantially tubular shape terminating with a plurality of tongues 5 A arranged to penetrate into the tubular portion 7 A of the conveyor structure, and an expansion member 8 which interacts with said tongues 5 A to cause them to adhere to the inner surface 7 B of said tubular portion 7 A, so fixing it to the connection element.
- the part 2 also presents an annular seat 5 C to house a portion P of the upper edge of the tubular component 7 .
- the part 2 also presents a vertical seat 5 D for passage of a screw 9 for operating the expansion member 8 .
- This seat 5 D is open at a free upper portion 2 D of the connection element provided between the two webs 2 B and hence always easily accessible to an operator.
- the screw 9 engages in a threaded seat of a usual wedge element 8 A such that on tightening the screw 9 this wedge rises to widen the tongues 5 A and, vice versa, on loosening the screw 9 , it moves downwards to enable the tongues to return elastically inwards.
- connection element As the means for fixing the connection element to the tubular component are of expansion type and comprise an operating screw provided in a vertical position accessible from above, they are always easily operable with a single tool, whatever the position of the connection element itself.
- connection means could be formed in a different manner from that shown, but still conventional for a person skilled in this art.
- the tongues 5 A could be omitted and the wedge member 8 A could act directly against the inner surface of the tubular portion 7 A.
- both the wedge member 8 A and that portion of the connection element which interacts with the tubular portion 7 A can have any geometrical cross-section, for example circular, square or hexagonal.
- more than one component of the conveyor support structure could be fixed to the first part 2 .
